IMPROVEMENT IN SUBMARINE FLOWS.

' OOO- The Schedule referred to in these Letters Patent and making pm of the same.

To all whom it 'may concern:

Be itknown that we, Amos MORRISON and RUFUs ROSE, lof New Orleans, in the parish of Orleans and State of Louisiana, have invented a new and improved Submarine Plow; and we do hereby declare that the following is a full, clearand exact description thereof, whichwill enable others skilled in the art to make and use the same,'reference being had to the accompanying drawing forming part of this speciication.

. The drawing represents a improved submarine plow.

This invention relates toa new construction of ship, for removing the earth from the bottoms of rivers, banks in harbors, Ste., and gathering it in fsnit'able receptaclesor scattering it, to,be carried away by the currents.

perspective view of our The invention consists in the arrangement with the l' plow-share, formed on the lower part of the' bow of the boat, of tubes and screws, for removing or elevating the earth taken np by the plow, as hereinafterdescribed. y

The boat A is constructed in such manner that it can be raised or lowered, at will, by discharging orY .taking in water ballast, and is provided with suitable propelling apparatus.

At the lower end of the bow, below the keel', is secured to ita plow-share, B, which is divided in the middle by 'an elevated 'ridge or cutter, to throw the earth which it works up to two sides.

C C are' two'tubes, secured to the sides of the boat y in inclined positions, so that their upperends reach above the waterlevel, while their funnel-shaped lower ends are directly behind the plow-shares.

The earth taken in bythe plow is worked into the tubes C, and, in the same, elevated by means of screws D D, which are revolved by suitable machinee ry from the boat.l The earthis, thereby, as the boat progresses, elevated in continuons streams, .and is, at the upper ends of the tubes, either returned to the water or dumped intoA receptacles to be carried away, It' the earth is thrown into the water, it is, by the current, carried away, so as to thereby bev removed from the bank. A.

This invention should notA be confounded with a dredgingfmachine, which is stationary, while our boat operates only when in motion, to apply its own force to the displacement'of the sand.

Having thus described our invention,

We claim as new and desire to secure by Letters
